IRRIGATION-PIPE.

To all 'whom t may concern Be it known that I, lsAAo B. Narnon, a citizen of the United States, residing at New York, in the county of New York andk State of New York, have invented certain new and useful improvements in irrigation- Pipes, of which the following 1s a specificaln irrigating land, the pipes are carried dilerent distances and outletsare provided at certain distances apart, either direct from the pipe or lateral pipesfare tapped into the main conduit to carry water the desired distance from the main pipe, and in many instances the discharge o-f water is through unprotected perforations slots or nozzles,

which results in sand and other foreign substances being washed into the pipes when there is no discharge from the pipes, whereby the pipes become cloggedv and some times closed, thereby seriously interfering with irrigating the land.

The object of my invention is to provide4 an outlet for an irrigation pipe which is of a construction to prevent the entrance of sand and other foreign matter into the water pipe through the outlet.

A furtherobject of my invention is to provide an improved outlet for irrigation systems where the water in the system is under pressure; and with these and minor objects in view, my invention consists of the parts and combination of parts as will be A, hereinafter pointed out.

' ln the drawings Figure l is a perspective view of a pipe unit embodying my invention; Fig. 2 is a longitudinal vertical section of the same; Fig. 3 isl a top plan view of Fig. l; Fig. 4 is a perspective view of a tion pipes 8 are connected to the main supply pipe. At the end or at suitable intervals throughout the length of each of the laterals, I introduce by improved discharge Specification of `Letters Patent.

unit 4. ln manufacturing this discharge unit, l prefer to havethe length of the main flow pipe 5 equal the'height of the discharge nozzle (i, plus the diameter of the main flow pipe. The main iow pipe 5 of the discharge unit is provided with screw threads at each end, whereby it may be joined with a watertight joint to the other sections of the pipe.` 7 1s a discharge port leading from the` main flow pipe 5 t0 divert water therefrom. The discharge nozzle comprises a casing 8 having discharge ports 9 in its side walls at the base thereof, a pipe 10 centered in said casing and forming a continuation of the discharge port 7 in the main flo-W pipe lt will be noted that the top of the pipe 10 terminates short of the casing 8 in order that there maybe an overow or Spill space between its top and the bottom face of the cap l1, said cap being screw-thread-` ed to the upper end of the nozzle casing 8.

12 are partitions arranged in the space between the casing 8 and the pipe l0 dividing said space into four channels 13, at the bottom of each of which is one of the ports 9 in the casing. It will be noted, more clearly in Fig. 3, that the tops of the partitions 12 terminate short of the top of the nozzle pipe l0, which results in a better distribution of the water from the pipe 10 into the several channels 18. I may, if found desirable, form a ball seat 14 onthe top of the pipe 10a and seat a ball 10b therein to serve as a valve, as shown in Fig. 6.

l may, if it is found desirable, form a baffle l5 in the pipe 5a, disposed transversely of the pipe, as shown in Figs. 4 and 5, the I object of which is to throttlefthe main passageway at a point in juxtaposition to each lateral port 7. 4'

From the above description, it will be seen that sand and other foreign matter cannot enter the nozzle pipe, nor main How pipe, and that if sand, etc., should accumulate around the ports 9, the weight of the column of water in the channels plus the velocity of the water will be suflicient to clear said ports 7 from all obstruction.

What I claim is l. In an irrigation system, a discharge nozzle comprising a main flow pipe having a port therein, a casing extending from said pipe and surrounding said port, a discharge nozzle pipe connected to and leading from said port to a point short of the top of the casing, channels formed between the nozzle lpipe and casing, and a port through said a discharge port, `a casing surrounding saidy port and extending at right angles from said pipe, a cap for said casing, a nozzle pipe leadinO' from said ort and'extendinO to a point short of the top ofthe casing, said nozzle pipe being concentric ywith the casing, partitions dividing the space between said casingk and nozzle pipe into channels, and a port at the bottom of each channel, said ports beingso disposed as to lead the water to opposite sides of the casing leading through the wall of thecasing.

v3. A discharge nozzle for an'kirrigation Copiesi'fthis patent may `be obtained for system comprising a inain flow pipe having a discharge port, a casing surrounding said port and extending at right angles from said pipe`a nozzle pipe within said casing and leading from the said port to a point short of the top of the casing, said nozzle pipe and casing being spaced 'from each other, partitions dividing the space between the casing and nozzle pipe into channels, a port at the bottoni of each channel leading through the `all of the casing, Vsaid ports being so disposed as to lead thewater to opposite sides of the casing, said partitions terminating short of the top of the nozzle pipe.

In testimony whereof I affix my signature in presence of two witnesses.
